Is 3.222222 a rational number

Mathematics
1 answer:
SIZIF [17.4K]3 years ago
4 0

Answer:

<h2>YES</h2>

Step-by-step explanation:

If the number is rational, I can write it as a fraction in which the numerator and denominator are integers (denominator other than 0).

3.\underbrace{222222}_{6}=\dfrac{3222222}{1\underbrace{000000}_6}-\bold{RATIONAL}

If is repeating:

x=3.2222....       <em>multiply both sides by 10</em>

10x=32.2222...      <em>    make the difference 10x - x</em>

10x-x=32.2222...-3.2222...

9x=29             <em>divide both sides by 9</em>

x=\dfrac{29}{9}-\bold{RATIONAL}

Let f(x) = 4x - 5 and g(x) = 6x - 3. Find f(x) - g(x).
professor190 [17]
F(X) = 4x - 5
G(X) = 6x - 3

F(x) - G(x)

(4x - 5) - (6x - 3)

4x - 5 - 6x + 3

-2x - 2

-2(X + 1).

I believe this would be the simplified solution.

Let A = {the Rationals) and B = {the Irrationals). Find AU B.
anzhelika [568]

Answer:

Option B.

Step-by-step explanation:

It is given that

A = {The Rationals}

B = {The Irrationals}

We need to find the set A∪B.

If we have two sets X and Y then union of these sets (X∪Y) contains all the elements of set X, of set Y or both.

It is given that A is the set of rations and B is the set of irrational, so the union A∪B is the combined set of all rational or irrational numbers.

A∪B = {The Rationals} +  {The Irrationals}

A∪B = {The Reals}

Therefore, the correct option is B.

How to simplify <br> -6k +7k<br> 12r -8 -12<br> n -10 +9n -3<br> -4x-10x<br> -r -10r
Semmy [17]

Answer:

Solve by adding or subtracting like terms. (Ex. 2k + 4k = 6k; 9 + 7 = 16)

- 6k + 7k = 1k = k

(7 - 6 = 1)

12r - 8 - 12 = 12r - 20

(8 + 12 = 20 but sign is negative) 12r will stay the same because there are no terms with a letter r.

n - 10 + 9n - 3 = 9n + n - 10 - 3 = 10n - 10 - 3 = 10n - 13

(n = 1 so 9 + 1 = 10; 10 + 3 = 13 but negative sign)

- 4x - 10x = 14x

(10 + 4 = 14)

- r - 10r = 11r

(r = 1 so 10 + 1 = 11)
